了解在線測試儀的讀者，均知道有這么一句行話。“在線測試時不通過的芯片不一定是損壞的；測試通過的芯片一定是沒有損壞的。”它的解釋為，如器件受在線影響或抗干擾時，結果可能不通過，對此不難理解。那么，是否損壞的芯片在進行測試時，均會得出“不通過”呢？回答確實不能肯定。筆者與同行均遇到過，明明芯片已損壞了（確切地說換上這個芯片板子就不工作了），但測試結果是通過的。權威解釋為這是測試儀自身工作原理（后驅動技術）所致。故此我們不能過分依賴在線測試儀（盡管各廠家宣傳的很玄）的作用，否則將使維修電路板的工作誤入歧途。
維修技巧之二　
　　在無任何原理圖狀況下要對一塊比較陌生的電路板進行維修，以往的所謂“經驗”就難有作為，盡管硬件功底深厚的人對維修充滿信心，但如果方法不當，工作起來照樣事倍功半。那么，怎樣做才能提高維修效呢？根據我公司進口設備維修中心統計出來的資料，應遵循以下幾個步驟、按順序有條不紊的進行。
方法一：先看后量
使用工具：萬用表、放大鏡
當手拿一塊待修的電路板，良好的習慣首先是應對其進行目測，必要時還要借助放大鏡，看什么呢？
